1 Claim. 1

The present invention relates to wrenches, and has special reference tohand wrenches for shoe calks.

The principal object of the invention is to provide a device of thischaracter which may be conveniently used to install or remove shoe calkshaving either a spanner grip or a lug grip, and which is of simple andcheap construction.

The invention is illustrated, by way of example, in the accompanyingdrawings, in which:

Figure 1 is a view in perspective of the wrench in its preferred form;

Fig. 2 is a longitudinal sectional view of the wrench shown in operativeengagement with a shoe calk of the spanner grip type, the shoe calkbeing shown in dotted lines;

Fig. 3 is a similar view of the wrench in operative engagement with ashoe calk of the lug grip typ and Fig. 4 is a sectional plan view, takenon the line 4-4 of Fig. 3.

My improved hand wrench as illustrated in the drawings may be made of asingle piece of sheet metal. As shown, the wrench is provided with aflat work-engaging head 2 which is provided with a key-hole shapedsocket 4 for operatively engaging a shoe calk of the lug grip type, andprotruding lugs 6 on its forward edge for operatively engaging a shoecalk of the spanner grip type. The socket 4 has its restricted portionsarranged in the longitudinal center of the head 2, and the forward edgeof said head is provided with a V-shaped cutaway opening 8 leading intothe socket 4 to provide a clearance opening for the point of the shoecalk when the wrench is engaged with a spanner type shoe calk. Thelongitudinal edges of the head are inclined inwardly toward its forwardedge.

The shank of the wrench has its inner end portion l arranged at rightangles to the head 2, and the remaining portion I2 of the shank isinclined upwardly and rearwardly at a convenient angle from the portionI0 and is curved to provide a comfortable hand grip.

With this construction, the transversely curved shank of the wrench maybe conveniently grasped 2 with the inner end portion ll! of the shankfirmly gripped between the thumb and forefinger, the position of thewrench in the hand being reversed with respect to the sides thereof forthe difierent type shoe calks. The head of the wrench is of proper sizeand shape and the shank of the wrench so formed as to provide clearanceon the shoe sole, ease of application and comfortable hand grip.

As will be evident to those skilled in the art, my invention permitsvarious modifications without departing from the spirit thereof or thescope of the appended claim.

What I claim is:

A hand-wrench for shoe calks of both the lug grip and spanner griptypes, made from a single piece of sheet metal and provided with a.flattened head having a slot therein, the rear portion of said slotbeing of keyhole shape and extending lengthwise of the head and thewalls of the forward portion of the slot extending outwardly andforwardly from the forward end of said keyhole shaped portion to formforwardly projecting arms, the ends of said arms being provided withREFERENCES CITED The following references are of record in the file ofthis patent:
